Well, some of the maps give really not assurance of safety. Like Tabara Quarry, if you're infantry well then you're screwed because there are a lot of tanks. If you're in a vehicle or tank, watch out for the bombers. If you are a jet, well watch out for the AA. Jets have it the easiest if they can evade the mobile AA and kill it often.
Great Wall is the best ground map ever. The walls give infantry an edge over tanks, which usually dominate on all maps. Mines can pretty much keep any armored convey from entering the fortress, unless someone is willing to take one for the team and drive over them. Getting out and removing enemy mines can be risky, so basically the tanks are just sitting on the other side of the wall while they try and kill stuff.
All I have to say though is that EF didn't deliver well. Its presentation as a new European Army got plenty of people shook up for it, but when people played the EU, they didn't get the impression it was really European. A lot of people laughed at the EF. I know a lot of people who won't buy EF because (not to offend anyone) they think Europeans are pussies. So it's an American thing, which is wrong and shallow. I personally like the Euroforces, and I'm glad we have allies like them. If ever BF2 were to become true, I wouldn't have it any other way, so I just feel proud when I play EF that's all.
So you got folks like me and others who are pleased with EF, but a lot of us want more. Like Snake said, it isn't much money. If you don't like it, it's not like you are flushing a bunch of money down the poop pot. Give it a try. Yea, there are some things you are going to dislike, or even hate, in Euro Forces, but there is also a lot you're just going to love. It's with all maps.
